During the production process, we may see staff wearing glasses. These glasses are protective glasses, which are divided into two categories: safety glasses and protective masks. The men sunglasses main function is to protect the eyes and face from electromagnetic waves such as ultraviolet, infrared and microwave. Damage from radiation, dust, fumes, metal and gravel debris, and chemical solution sputtering. So let's understand what is the use of labor protection glasses and how do we choose the right one?

1. Protective glasses against solid debris

It is mainly used to prevent mechanical damage to the eyes such as metal or sand and gravel debris. Spectacle lenses and frames should be sturdy and shock resistant. The frame is surrounded by a hood, which should have ventilation holes. Protective lenses are available in tempered glass, glue-bonded glass or copper wire mesh protective glasses.

2. Protective glasses against chemical solutions

Mainly used to prevent chemical damage to the eyes from irritating or corrosive solutions. Ordinary flat lenses can be used, and the frame should be covered to prevent the solution from splashing in. Usually used in laboratories, hospitals and other places, general medical glasses can be used.

There are many types of protective glasses, including dust-proof glasses, impact-proof glasses, chemical-proof glasses and light-radiation-proof glasses. The first three glasses look like the lenses are colorless glass, but in fact, due to different protective effects, the characteristics of the lenses are significantly different.

Some workers who are engaged in industrial production need to wear glasses to operate. Wearing such glasses is not for decoration and fashion, but to protect the eyes from harmful factors. Therefore, such glasses are called safety glasses.

Workers engaged in electric welding, gas welding, steel making, and glass blowing should wear anti-arc radiation glasses. However, the color of the lenses of the anti-arc radiation glasses is dark or light, which is designed according to different requirements, and the selection should be appropriately selected according to the strength of the arc during the operation. The arc light is strong and the color should be dark; otherwise, light-colored lenses should be selected. If the arc light is strong and light-colored safety glasses are worn, part of the infrared rays will stimulate and damage the eyes through the lens, and occupational cataracts will occur in the long run; on the contrary, if the arc light is weak and dark safety glasses are worn for a long time, vision will be greatly reduced.
